Duhamel procedure is done for
**Core Concept**
The Duhamel procedure is a surgical technique used to treat anal anomalies, specifically anorectal malformations. It involves the removal of the distal portion of the rectum and the creation of an anastomosis between the remaining rectal stump and the anus. This procedure is typically performed in cases of high imperforate anus.
**Why the Correct Answer is Right**
The Duhamel procedure is performed to address the underlying anatomical defect in anorectal malformations. The procedure involves the removal of the distal rectum, which is usually ectopic and not in its normal position, and the creation of an anastomosis between the remaining rectal stump and the anus. This allows for the restoration of normal bowel function and the creation of a continence mechanism. The procedure is typically performed in cases where the rectum is not in its normal position, such as in high imperforate anus.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the Duhamel procedure is not typically performed for Hirschsprung's disease, which is a different type of congenital anomaly.
**Option B:** This option is incorrect because the Duhamel procedure is not a treatment for rectal cancer, which requires different surgical approaches.
**Option C:** This option is incorrect because the Duhamel procedure is not a treatment for fecal incontinence, which is a symptom that can result from various causes.
**Clinical Pearl / High-Yield Fact**
The Duhamel procedure is a type of pull-through procedure, which involves the removal of the distal rectum and the creation of an anastomosis between the remaining rectal stump and the anus. This type of procedure is typically performed in cases of high imperforate anus and is associated with a good long-term outcome.
**Correct Answer:** C.
